A比B + adj + 一点儿 vs A比B + adj + 得多: quantifying the difference
Both structures are used after a 比 comparison to indicate the size of the gap between two items. 一点儿 means 'a little bit more' and emphasizes a small difference, while 得多 means 'much more' and emphasizes a large difference. They are placed directly after the adjective, not before it.
When making comparisons with 比 (bǐ), you can specify the degree of difference using 一点儿 (yìdiǎnr) for a small margin or 得多 (de duō) for a large margin. Both are placed after the adjective. 一点儿 indicates that A is only slightly more [adjective] than B, while 得多 indicates a significant difference. These structures are mutually exclusive for expressing degree – you cannot use both at once. Note that 很多 (hěnduō) is also grammatical after the adjective (e.g., 他比我高很多), but 得多 is the standard degree complement taught in textbooks and more common in this pattern.
When to use each
Use this when you want to emphasize that the difference between A and B is small, slight, or marginal. It is neutral in register and common in everyday speech.
In more formal writing or careful speech, 一些 (yìxiē) may be used instead of 一点儿 for the same meaning.
Use this when you want to emphasize a large or significant difference between A and B. It is the standard way to express a big gap in a 比 comparison.
In colloquial speech, 多了 (duō le) is often used in place of 得多, especially in northern Mandarin. For example, 他比我高多了. Both are correct, but 多了 is considered less formal.

Common mistakes
- Placing 一点儿 or 得多 before the adjective: ✗ '他比我一点儿高' should be '他比我高一点儿'.
- Using 一点儿 when the difference is actually large, e.g., saying '他比我高一点儿' when he is a foot taller – that would understate the difference.
- Using 很多 instead of 得多 is not wrong, but learners may avoid it because textbooks emphasize 得多; both are grammatical.
- Confusing 一点儿 with 多: '他比我多高' is incorrect because 多 cannot directly combine with height; the correct structure is '高得多'.
FAQ
- When do I use 一点儿 vs 得多 in a 比 comparison?
- Use 一点儿 when the difference is small or slight, and 得多 when the difference is large or significant. The choice depends on the actual gap you want to describe.
- Can I use 很多 instead of 得多 after the adjective?
- Yes, '他比我高很多' is perfectly grammatical and common in spoken Chinese. However, 得多 is the standard degree complement taught in textbooks and is equally natural. There is no rule against 很多.
- What is the difference between 一点儿 and 一些 in this pattern?
- 一点儿 and 一些 can often be used interchangeably after the adjective in 比 comparisons to indicate a small difference. 一些 sounds slightly more formal and is preferred in written Chinese.
- Can I place the quantifier before the adjective, like '他比我一有点儿高'?
- No. The quantifier (一点儿, 得多, 很多, etc.) must come directly after the adjective, not before it. '他比我一有点儿高' is ungrammatical because the quantifier is placed before the adjective and also incorrectly splits the object.
